L To all whom it may concern:

Be it known that we, Josnrn lV. BROD- BECK and Cinnamon J. Uncanny, both citizens of the United States, and residents of Cincinnati, Hamilton county, State of Ohio, have invented a certain new and useful Nurser -Powder Compound; and we do doclare t e following to be a clear, full, and exact description of the invention.

This invention relates to powder compounds of the kind used externally and applied to the surface of the skin like some of the powder compounds now on the market and known as baby or nursery powders. The general object of these powders is to protect thesurfacc oi the skin, to inducev the healing 'ofsore and galled portions thereof, and to prevent the skin from becoming sore in consequence of moisture due to natural discharges in cases of the sick, children and babies, etc.

Powders now on the market have the in herent defect that moisture due to natural discharges was hesthem oil and carries them quickly way, denying the skin ti'iereaftcr unprotected, th same as if no powder had been applied, thus utterly failing; in the .inziinribject oi. their use.

We have discovered that SLL'HI'lG acid when combined with hoses and derivatives of zinc and applied in poiwler-i'm-m to tho surfaco of the-skin, adheres readily thereto and forms a protective layer which is impervious to ,water and readilyshods n'ioisllirc, urinc for instnce, in caso of babies, Without being carried away thereby, so that the skin remains perfectly dry. The most convenient form in which this substauco may be obtained is the, commercial stcaratc of zinc such vas is purchasahlo in the markets. The effect of this subs-tarmac is inciwascdby addition to it of approximatvly an qual quantity of oxid of zinc in powdoi i'oru'i which is: likewise insoluble in. water and adds hraling and antiseptic properties and in case of open sores has a cooling oll'col'. it. is not necessary that. these sulmtancas ho applied to the skin in their normal state and by preference they arc combined with a suitable base which may serve as a vehicle, such as talcum-powder for instance, or its cquiv- I alent, and in proportions from about two and one half to three times as much as the two reviously mentioned substances combined? To this mass we add a pure antiseptic, such as h'oracic acid and an astringent such as salicylic acid or their equivalents. This entire mass is now thoroughly intermixed to form an ilnpalpablc powder to which a suitable perfume may be added.

before stated the stearate of zinc assisted by the oxid of zinc forms a moistureproot' coating which, by adhering; to the skin, protects the some and maintains it. in a dry state. in cases where the skin is sore, galled or o ion, the healing process is induced and tavored by the presence of tho astringent medium which is salicylic acid which also tends to dry up discl'mrging sores, the. healing action proceeding under the protection due to the presence of the antiseptic medium which is horacic acid.

A preferable com position as to proportion consists oil slearato of zinc, oxid of zinc and boraoic acid, each in equal quantity and combined with about double their coi'nhincd quantity of" the vehicle which is usod and which, as before stated, is talcum powder. To this is added a small quantity of salicylic acid, about from one half to one per cent. of: the entire mixture.

llhilc this po'wdor when applied to the skin forms a protective layer which is moisrcmovod and washed as. with water when soap is athlod:
